Abstract

Early blight is one of the most common and destructive diseases in tomatoes caused by the fungus Alternaria solani. Antifungal activity of six botanical extracts, namely (Datura stramonium) Datura, (Polyalthia longifolia) Ashoka, (Clerodendrum viscosum) wild jasmine, (Eucalyptus globulus) eucalyptus, (Chromolaena odorata), Siam weed extract, (Lantana camera) wild sage extract was antifungal. Each plant extract tested against Alternaria solani, with two concentrations, 5% and 10%, under in vitro and in vivo. The maximum decrease in the growth of mycelium of Alternaria solani with Eucalyptus globulus and Lantana camara (67.68% and 36.72%, respectively) and the minimum disease intensity under in vivo were recorded with Eucalyptus globulus (27.42%).
